Applieation ned December 24, 1923. serial No. 682,424.

with the accompanying drawings, is a full,

clear, and exact description.

Thisinvention relates to steamand hot water heatersrof the upright hollow section type and Yrefers more particularly to the means for-supporting and operating the grate bars and their relation tothe draft and clean-out openings of the ash pit.

In heaters of th'vs character, considerable difficulty is experienced in the free opera-` tionof the grate bars owing to the accumulations of ashes, clinkers and coal upon the gearsI or other connections by which rotary motion is transmitted from one grate bar to another.

" Furthermore,A it is Idesirable to provide means for 'turninglthe grate bars by hand from the front of the heater and at the'same` time to extend the grid portions of the bars under theV entire area' of the combustion chamber land when the gears or other connections for transmitting motion from one grate bar to another are lmounted upon the front ends of the bars, it `isnecessary to'reduce the grid length of the bars or to lengthen the front end of said bars for convenient lmanipulation by the usual hand cranks.

The main object therefore, of our present invention is not only to avoid the Vcollection of ashes, clinliers and coal upon the mechanism for transmitting motion fromr one bar to the other, but also to avoid the neoessityfor shortening the grate bars or lengthening the frontends thereof for operation bythe khand crank and at the same time, enabling the grid portions of the bars toV extend across the entirevbottom of the combustionV chamber.

'l Another: objecty is. to provide Vmeans whereby the grate bars may be conveniently and expeditiouslypremoved for repairs or other purposes without displacingthe gears from their housing and also `to permit the ,-parts'of the heater will be brought Vmy invention.

'Other' objects and uses relating to specific out in thefollowing description.

-and -3- arranged face to ,face in sequence from front to rear and clamped together by suitable tie rodsl or bolts -.4- which are passed through registering openings in uncored portions of the bottom and topwalls v ".of` said sections at opposite sides of their -vertical centers wherey they are protected against deteriorationfby the heating fluid or by the products of combustion, and also permit limited expan'sionandy contraction of the sections `without overstraining the bolts.

.Thecentral and lower portions of the intermediate .sections -Qfare provided with similar registering openings from front to rear to form a combustion chamber -5- and jan' underlying ash pit -6- and also to Vreceive 'a plurality vof grate bars -7- forming the -bottom of -the combustion chamber and top of the ash pit. The vvfront'vand rear sections-4 and -'3-" extend across and constitute the front lfand'r'earlwalls'of the combustion chamber 5-`^-5 'andl ash pit .-6- and have their inner sides ehambered to conform in outlinewith the openings in the vintermediate section lto'form continuations of the combustion chamber -5-y and ash pit --6-.

It is now clear that the front wall of the rear section -3- in which the rear ends of the grate bars are j ournaled forms the rear wall of the combustion chamber ,-5- and protects the gears --32. from contact with the ashes, clinkers or coal in the combustion chamberA and also from the water of all of the sections and brings the gears wholly within the cross sectional area of the` rear section thereby avoiding the necessity for elongating the front ends of the grate bars and on the whole, affording a more compact assembly o-f the sections of the heater.

It is also evident that by opening the door 23# and removing the angle plate -28-,

the grate bars may be removed forwardly without displacing the gears -32- from the pocket -31-, it being understood that the rear ends of the bars are angular in cross section and are slidably inserted. in similar openings in the gears to permit such withdrawal. g

Under this construction, the gears .32-

may be withdrawn from the rear ends of the grate bars by simply removing the plate -33- and then sliding the gears rearwardly v from the adjacent ends of the bars,l all of which contributes to the economic assembly of the grates and also to the economic withdrawal of the grates or gears for repairs and at the same time avoids any possibility rof clogging the gears by the accumulations of ashes or clinkers thereon.

The placing of the gears on the rear ends instead of on the front ends of the grate bars within the pocket -31- Where they are protected by the inner wall of the rear section -3-, leaves a free open space at the front along the lower and upper faces of the grate bars for loosening and removing clinlers and ashes and permits the use of an ash pan in the ash pit when desired withoutk in any way interfering with the gears.

The operation of our linvention will now be readily understood upon reference to the foregoing description and accompanying drawings, and while we have shown and described gears as the meansv for transmitting motion fromvone grate bar to the other, it is evident that other means' may be employed in the pocket -31- and that the front ends of the'grate bars may be otherwise supported,without departing from the spirit of this' invention.

We claim: Y

1. An upright sectional boiler-having one of its end sections p-rovided with water legs forming portions of opposite sides of the combustion chamber and ash pit and provided With a gear chamber in its outer end face at a level between the combustion chamber and ash pit and between the water4 containing legs, grate bars extending thru openings in the inner wall of the gear chamber, and gears mounted on the grate bars within the gear chamber.

V2. An upright sectional boiler having one of its end sections provided with water legs forming portions of opposite sides of the combustion chamber and ash pit and provided with a gear chamber in its outer'end face at a level between the combustion chamber and ash pit and between the water containing legs, grate bars extending thru openings in the inner wall of the gear chamber, gears mounted on the grate bars within the gear chambenand a cover plate secured to said end section across the outer end of the gear chamber for concealing the gears therein. l Y

3. An upright sectional boiler having one of'its end sections provided with water legs forming portions of opposite sides of the combustion chamber and ash pit and provided With a gear chamber in its outer end face at a level between the combustion chamvber and ash pit and betweenthe water containing legs, grate bars extending thru openings in the inner wall o-f vthe gear chamber,

and gears mounted on the grate bars within the gear chamber, said gears being splined on the adjacent ends ofthe respective grate bars for axial removal therefrom.

In witness whereof We have hereunto set our hands this 11th da of December, 1923.
